Specification of Letters Patent.

Patented Mar. '7, 1916.

Application led April 12, 1915. Serial No. 20,899.

To all whom t may concern Valves, of which the following is aspecilication, reference being had therein to the accompanying drawings.

The invention relates to valves andresides in the novel connectionbetween the valve casing and the valve stem, and ink certain details ofconstructions, arrangements and combinations of parts as will more fullyhereinafter appear.

In the drawings,-Figure I is a longitudinal, central section through avalve embodying the invention; Fig.Y 2 is a sectional plan view thereof;and Figs. 3, 4 and 5 illustrate certain details of construction.

A designates the casing of the valve and B the plug valve therein, theseparts for the purpose of the invention being of any suitableconstruction'. In the structure shown, however, the valve Vis of theshell type.

C is the inlet for the casing and D the outlet. f y

E is the valve opening, which upon rotation of the valve is adapted tobe moved into 0r out of registration with the outlet D. Rigidly attachedto the valve isv a stem F that extends out through the neck G of thevalve casing. Within the neck G is a bearing II having a centralaperture I of a size to nicely it the stem.

J is an opening'in the bearing communieating with the aperture I, and Kis a lug on the valve stem adapted when the latter is inserted throughthe aperture I to pass through the opening J, so as to be positionedabove the outer face L of the bea-ringH.

M is a key which closes the opening J.

`With the parts so far described, when it is desired to engage the valvewith the casing, th-e stem is inserted thro-ugh the aperture I and afterthe lug K passes above the outer ace'L of the bearing II, the stem isrotated to move the lug K out of registration with the opening J and thekey M then inserted into the opening J. The valve is supported from thebearing II by the lug K. Below thelug K is a shoulder N spaced from thelug a sufficient distance to allow the bearing Yto be positionedtherebetween.

When the key is insertedin the opening J the lower edge of the key restsupon the shoulder N. have stops for positioning the opening and closingmovements of the valve, and to this end the keyM is made of a suilicientlength to proj-ect above the bearing H into the path of the lug K, sothat when the valve' is turned in one direction its movement will belimited byk thelug K contactingwith one side of the key M, while kwhenturned in the opposite direction the movement will be limited bythe lugK contacting with the opposite side of the key. The parts are soproportioned that in the ldiiferent positions of contact of the lug withthe key, the valve will be in its openiand closed positionsrespectively.

It is of course, desirable to The neck G is provided with the usual ygland nut O having the packing material P. Below the packing l? isarranged a washer Q which seats on a ledge R in the upper edge of theneck G. By this arrangement the packing kI) may be tightly compressedwithoutin any way Vafecting the connection between the valve stem andthe neck G.

The form of valve described is a very simf from and engaging theouterface of said bearing, said lug being of a size to be insertedthrough the opening, and akey insertible through the neck portion forclosing said opening.

2. In a valve, the combination with the casing havingV a neck portion, acentrally apertured bearing in the neck portion having an openingtherethrough communicating with the aperture, a plug valve within thecasing, a stem for actuating said valve arranged within the aperture ofthe bearing and having a lug projecting laterally therefrom and engagingthe outer faceof said i bearing,'said lug being of. a size to beinportion,

serted through the opening, and a key for apertured bearing in the neckportion, said bearing having a flat outer face and provided With anopening therethrough communicating with the aperture, a plug valveWithin the casing,a stem for actuating said valve arranged Within theaperture of the bearing and having a lug projecting laterally therefromand engaging theV outer face of the bearing, said lug beingof a size tobe inserted through the opening, and a keyfor closing said openingprojecting above the outer face of the bearing and positionedto formstops coperating With the lug to limit the opening and closing of thevalve.

4; In a valve, a casing having a neck a centrallyv apertured bearingformed Within and integral With the neck portion, said bearing having aflat outer face and provided with an opening therethrough, a plug valveWithin thecasing, a stem for actuating said valve arranged Within theaperture of the'bearing, a shoulder on the stem below the bearing, a lugon the stem engaging the outer face of the bearing and acting to supportthe valve, said lug being ofa size to be inserted through said opening,and a key insertible Within the opening and supported upon saidshoulder, said key projecting above the outerfface of the bearing intothe path of the lug and forming stops for limiting the opening andclosing of the valve. Y

5. In a valve, the combination With the casing having a neck portion, acentrally apertured bearing in the neck portion having an openingtherethrough communicating With the aperture, a plug valve Within thecasing, a stem for actuating said valve arranged Within the aperture ofthe bearing andhaving a lug projecting laterally therefrom and engagingthe outer face of said bearing, said lug being ofv a size to be infserted-through the opening, a key for closa collar engaging said seatand against yWhich the packing is forced.

6. In a valve, the combination With a casing having an apertured bearingprovided With an opening therethrough communicat- Ving Withthe aperture,a plug valve within the casing, a stem for actuating said valve,

arranged Within the aperture of the bearing and having a lug projectinglaterally therefrom and engaging the outer face of said bearing, saidlug being of a size to be inserted through the opening, and a. closurefor the opening.

7 Ina valve, the combination with a casing having an apertured bearingprovided with an opening therethrough communicat- .ing With theaperture, ay plug valve Within the casing, a stein for actuating saidvalve, arranged Within the aperture of the bearing and havinga lugprojecting laterally therefrom and engaging the. outer face of saidbearing, 'said lug being of a size to be inserted through the opening,and a closure for the opening, and means for limiting the motion of thevalve. Y

8. In a valve, the combination With a casing having a neck portion, acentrally apertured bearing in the neck portion having an openingtherethrough communicating With the aperture, a plug valve Within thecasing, a stem for actuating said valve arranged Within the aperture ofthe bearing and having a lug projecting laterally therefromengaging theoutery face of the bearing, said lug being of a size to be insertedthrough said opening, a key for closing said opening, and a shoulder onthe stem beloW the bearing. v I

9. In aV valve, the combination With a casing having an aperturedbearing provided 'with an opening therethrough communicating with theaperture, a plug valve Within the casing, a stem'for actuating saidvalve arranged Within the aperture of the bearing and having a lugprojecting therefrom and engaging the outer face of the bearing, saidlug being of a size to be inserted through the opening, and 4meansretaining said closure against displacement longitudinally of the stem.

In testimony whereof I affix my signature in presence of tivo Witnesses.
